From 3rd to 4th generation district heating – the engineering challenges

Who for?

System designers, M&E consultancies, M&E contractors, ESCOs, building facility managers, housing associations other interested parties, etc.




As a result of the proposed changes to the future treatment of district heating systems in SAP, together with the recent introduction of SAP10 carbon factors by the GLA for all new schemes, there is a clear drive towards lowering the operating temperature in district heating schemes in order to reduce thermal distribution losses and apply heat pump technology.

However, this shift from 3rd to 4th generation district heating systems brings several hydraulic consequences which should be taken into account carefully to ensure systems are able to return the economic and carbon saving efficiencies they promise.

In this webinar Roel Vandenbulcke, Hysopt founder and CTO, will point out the hydraulic and control technical aspects to be taken into account when designing 4th generation district heating schemes and emphasises the impact on the overall system efficiency.

Performance Gap - The High Cost of Low HVAC Performance
So, how can you overcome your building installations failing to live up to their anticipated performance?
Why your heating bills are higher than they should be!
Rising energy prices are the talk of the town. Meanwhile, the energy used to heat buildings represents approximately 70% of annual energy consumption, meaning tackling the costs of heating has become a top priority for owners and operators of buildings across the private and public sectors. So, what can you do?
